What is the Context of GKR Protocol?

The GKR protocol is a foundational element in the development of advanced zero-knowledge proof systems and verifiable computation. Current discussions often relate to its application in scaling blockchains and enhancing privacy-preserving technologies. Researchers are examining its integration with other cryptographic primitives to achieve greater efficiency and broader applicability in areas like private smart contracts and efficient data verification.

Definition

The GKR protocol is a cryptographic technique that enables efficient verification of computations. It allows a prover to demonstrate that a complex computation has been performed correctly without revealing the underlying data. This is achieved through a specific protocol that reduces the verification complexity.
